PatchPanel::clearPatchConnections deletes PatchRecord before
the peer PatchTrack is stopped. This can cause an access to already
free'ed memory leading to a crash in PatchTrack::getNextBuffer.
Fix is to delete PatchRecord and PatchTrack only after removing
both of them from active tracks list

Do not use setParameters() with AUDIO_PARAMETER_STREAM_ROUTING
when communicating the input or output device selected to playback or
record threads, even for HAL version less than 3.0.
Use createAudioPatch()/releaseAudioPatch() instead.
This allows to send more information on the output or input device being
selected.
Also fix a regression introduced in L where the output device selection
was not communicated to effects on record threads.

Allow creation of audio patches between input and output
devices managed by the same audio HW module.

Before the audio patch is created, audio patch with same handle is
removed from vector for patches. At this time, Patch allocated in the
heap is not freed. This causes memory leaks in the mediaserver.

Allow creation of audio patches with more than one sink.
More than one sink is enabled when:
- Connecting an input device to output devices on the same audio HW module.
- Connecting an output mix to output devices on the same audio HA module.
All other patches are limited to one sink.

Add parameters to openInput() and openOutput(): device address,
input source.
Allow caller to specify a given I/O handle
Group parameters in a struct audio_config.

Add support for audio device connections between different audio
hw modules.
The patch is performed by creating a bridge between the playback
thread connected to the sink device and the record thread connected
to the source device using a pair of specialized PlaybackTrack and
RecordTrack.
- Added PatchTrack and PatchRecord classes.
- Added TrackBase type to indicate more clearly the track behavior.
- A TrackBase can allocate the buffer or reuse an existing one.
- Factored some code in openOutput() and openInput() for internal use
by PatchPanel.

Implement setAudioPortConfig() API to configure an

Add implementation of audio routing control via AudioSystem APIs.
The following APIs are implemented:
- listAudioPorts(): return a list of devices and output/input mixers ports
that can be used as sources or sinks for audio patches.
- createAudioPatch()/releaseAudioPatch(): create/release a connection patch between
two audio ports (e.g. to connect input from an HDMI device to a speaker output device).
Only one client application can own a patch from a given source.
When an audio port (device or mix) is part of an application created patch, its routing cannot
not be changed by a policy decision.
- listAudioPatches(): return a list of existing patches.
Each audio port addition/removal and each audio patch creation/release increments a generation count.
This generation count is used to ensure consistency betwen calls to
listAudioPorts() and listAudioPatches().

Added a new PatchPanel subclass to AudioFlinger
to handle audio ports and audio patches configuration
and connection.
The first implementation does not add new functionnality.
AudioPolicyManager uses patch panel interface to control
device routing.
AudioFlinger:
- Added PatchPanel class. The first implementation does not
add new functionnality. PatchPanel handles routing commands
for audio HAL after 3.0 or converts to setParameters for audio
HALs before 3.0.
- Added config events to ThreadBase to control synchronized
audio patch connection.
AudioPolicyManager:
- Use PatchPanel API to control device selection isntead of setParameters.
- New base class AudioPort common to audio device descriptors
and input output stream profiles. This class is RefBase and groups
attributes common to audio ports.
- Use same device selection flow for input as for outputs:
getNewInputDevice -> getDeviceForInptusiource -> setInputDevice
